Kokushibo is the upper moon 2 of the twelve kizuki. He is also the user of the moon breathing technique and is the strongest demon after Muzan.
Kokushibo is also Yoriichi's older twin and he willingly chose to be turned into a demon.
The Hashira are the pillar of defense against Muzan and his demons. They are the strongest demon slayers.
There are a total of nine Hashira. Every single member possesses a unique breathing style, but the fire and water-breathing user has always been a part of the Hashira.
In an all-out between the strongest demon after the demon king himself and the pillars of defense that humanity has, the Hashira will win.
Kokushibo is undoubtedly strong and it will be quite difficult for the Hashira to defeat him, but they will be able to. Gyomei alone was able to give great trouble to Kokushibo in their fight
In addition to their physical prowess, the Hashira can use Shinobu's poison against the upper moon to defeat him. Shinobu's poisons managed to defeat Douma.
It will be a very close battle, and many of the Hashira might lose their lives, but in the end, it is the pillars that will emerge victorious.
